Looking very nice filling the whole tent.
Have you done 4 in that tent before?
I have same tent size, growing three and the fourth spot is taken by the fan.
@6ix6ix6ix, first time doing 4 in this tent. I've ran 2 successfully with peppers, lettuce, spinach in the tent as well. I have a cheap clip on usb fan to move air in addition to the exhaust fan. I've noticed my humidity is high (probably from the crowding) and am thinking about getting a dehumidifier. May also do some defoliation for more air flow.
